While Groupon’s co-founders and high-level executives notoriously took hundreds of millions off the table in an earlier round of funding, they still had notable skin in the game today, as evidenced by the share allocation on Groupon’s latest S-1. Biggest winner? Lightbank founder Eric Lefkosky, who is now a billionaire three times over with a solid 28.1% voting share. CEO Andrew Mason, by comparison, is now worth $1.2 billion in Groupon stock.

VC firm Accel Partners and the Samwer brothers are also in enviable positions post IPO, each netting about a billion in Groupon equity for their troubles. It’s probably safe to say that just about everyone on this list is on a customary six month lockout with regards to selling their shares, and God only knows what the stock will be trading at then.

While we all wait, here’s a video of Mason and I back when he was cool wasn’t such a fancypants. [Hi Andrew :)]
